The queues for this attraction can get HUGE, we walked past there before it opened one morning and there were scores of people already waiting.
This was the big thing that I wanted to do on our trip, so we went up on the first night we arrived. It was about 6pm and we had to wait about half an hour but it was totally worth it. It was already dark by the time we started to go up, and there were christmas lights all over the city. Once you get out onto the platform it is just breathtaking.
We only went up to the first level but you still get a fantastic view, and there is a restaurant, cinema, some art displays, and of course a gift shop!
We weren’t brave enough to walk up the steps (it was windy!) but the lift is nice and it is cool to see the city falling away below you as you get further towards the top.
We also had a wander through the park one morning, it is small but pretty, and there is a little pond with ducks and other birds there.
